Strategies

A strategy is a recording of your board: which tower, on which cell, in the order you built them. Open Strategies from the pause menu and save the board you have; in a later run, choose it and press Activate, and from then on the game spends your money putting those towers back in that same order, one per tick, while a wave is running. A cell you already filled with the right tower is left alone, and so is one holding a different tower: the strategy only fills EMPTY cells, and never tears down what you placed. It obeys the same rules you do: a tower you have not unlocked this run is skipped, and so is one you cannot pay for. Whatever it is waiting on is written in the corner of the screen, and that notice is also the off switch. The Strategy+ node in the skill tree buys a second and a third saved board to choose between.
